This is a fairly basic concept that is cause for a slight - but important - misunderstanding that I want to clear up.

Unlike no-limit and pot-limit games, there’s little you can do to control the pot odds in limit poker except tricky stuff like getting innovative with checkraises or waiting until the turn to raise. This means that draws - even fairly weak draws - will often have correct odds to call and there’s exactly nothing that you can do to prevent that.

This is entirely true.

But, and this is the really important point, this does not mean that betting or raising isn’t profitable for you. If you’re 85% to win, and you make a bet into a pot containing 9 bets already, your (15% to win) opponent will be right to call your bet - but this doesn’t in any way, shape or form take away betting as the best alternative. For every dollar you can make him put into the pot, you get to keep 85 cents. Not bad.

If you bet into a 10 bet pot, and your opponent calls with proper pot odds, he won’t have made a mistake. However, neither have you. This is an important distinction.
